This is a 3D model based on sch00f's filament test cube. It's intended both for calibration and to illustrate how a filament works in a few different situations.
Features of the cube include:
There are a couple of example STLs included here, but it's really intended for use with OpenSCAD. If you want an unlabeled cube, you can just use sch00f's.
This works best with a development release of OpenSCAD and textmetrics() enabled in the preferences menu. It'll function without that, though you might need to manually tune the font size for the text on the underside of the cube.
The file defaults to a couple of my preferred fonts, but it'll fall back to OpenSCAD's built-in Liberation Sans if one or both of those isn't available.

The author remixed this model.
Added the ability to put the filament name in the cube. Also rewrote it in OpenSCAD.
